From what I've witnessed it was just a thing between Kronos and Lance with them messing with each other. I'm not validating his actions by any means but I wasn't aware that Kronos had an issue with it. They would both chuckle, however, I did see he froze Ro0 when he shouldn't have. I don't think Ro0 felt the same way Kronos did about the freezing during the knife fight rounds.
